Flow of Energy in Ecosystems

Think of climbing stairs, the higher you climb the less energy you have, so animals on the top of the pyramid only have a fraction of the energy that animals near the bottom of the pyramid do.

Roles in an Ecosystem

Think about Latin roots to remember what consumers eat.
Herba (herbivore): small plant
Carne (carnivore): flesh
Omni (omnivore): all

Biological Communities

To remember the difference between biotic and abiotic factors, know that the prefix “a” before a word means not. So if biotic factors are living, then abiotic factors must be non-living.

Climate Zones and Biomes

Think of the word “biome” as “bio-home”. A biome houses certain types of plants and animals.

Geographical Determinants of Climate

If you shine a flashlight on a basketball, you’ll notice that some parts of the basketball aren’t as bright as other parts. Similarly, the light from the sun hits the earth with greater intensity at some parts more than others.

Weather Maps

To remember the names of isolines, note the root words. Temperature is represented by “therm,” “bar” is a measurement of pressure, and “tach” is often associated with words relating to the measurement of speed.

Predicting Weather

Did you know that a 5-day forecast is just as accurate as a 2-day forecast was 20 years ago?

Collecting Weather Data

Weather reports on TV use all of these instruments to obtain accurate forecasts of the
weather.

Weather Fronts

Warm air rises, and cold air sinks. This will help you remember how cold fronts and warm fronts are formed.

Air Masses

The different types of air masses are like different moods. Depending on an air mass’s humidity and temperature, it can bring warm, friendly weather, or cold, icy storms.
